MARKER FOR CORN-PLANTERS.

Specification of Letters Patent.

Patented Feb. 12. 1907.

Application filed June 18,1906- Serial NO- 322.639-

To It whom it may concern.-

Be it known that I, AARON E. STARRETT, a citizen of the United States, residing at Kellogg, in the county of Jasper and State of Iowa, have invented a certain new and useful Marker for Corn-Planters, of which the following is a specification.

The object of my invention is to provide a marker designed to be pivoted to the rear of a corn-planter and to be capable of quick and easy reversal from one side of the machine to the other to produce a mark on either side of the machine, and, further, to provide means of simple, durable, and inexpensive construc tion whereby the operator on the drivers seat may quickly and easily throw the marker from one side to the other or maintain it in an upright position.

My invention consists in the construction, arrangement, and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 shows a plan view of a cornplanter provided with my improved marking device. The dotted lines in said figure show the marker in a reversed position. Fig. 2 shows a rear elevation of same. The dotted lines show the marker and marker-operating devices in position with the marker elevated.

Referring to the accompanying drawings, I have used the reference-numeral to indicate the marker-frame. Supportedilongitudinally of the frame near its rear end is a shaft 11, on the rear end of which is an arm 12, having a loop 13 at its outer end, and on the forward end of said shaft 11 is a crankarm 14, having a roller thereon. Fixed to the rear of the frame 10 are two supporting-arms 16, extendin .laterally and rearwardly, with upturne rear ends 17. The marker-arm comprises a body portion 18 and an extensionpiece 19, telescopically connected with it and having a marker-disk on its outer end. The inner end of said body portion is pivoted in a slotted in 21, so that the marker-arm may move orwardly and rearwardly relative to the marker 19, and the said pin is pivotally connected with the frame 10 to be capable of movement in a lane transversely of the frame. The said 00p 13 of the arm 12 encircles the said 1 marker arm, so that the marker arm is moved 1n unison wlth said arm 12.

An arched shaft 22 1s pivoted in the frame 10 adjacent to the crank-arm 14 and has its central portion curved or bowed forwardly, and on one end thereof is a lever 23, provided with a pawl 24 to engage a sector 25, fixed to the frarre 10, whereby the said lever may be locked in different positions. The arched shaft 22 is so arranged and disposed relative to the roller 15 that when the arched portion of the shaft is in a forwardly-inclined position the said roller will rest on one of the sides of said arched portion. Then when the lever 23 is moved rearwardly the roller will slide along the arch, and thus the crank-arm 14 will be elevated until the roller reaches the forwardly-inclined portion of the arch, and when the roller engages this inclined portion the crank-arm 14 will'be supported by said arch in a substantially vertical position, and this will also cause the n" arker-arm to stand in the same position. If the operator imparts a rapid movement to the lever 23 when the roller 15 is just ap proachirg the forwardly-curved portion of the shaft 22, then he will in part enough rrorrentum to the narker to throw it past the center and perrr it it to descend by gravity to the other side of the frame. This obviously may be done in order to move the marker from either side of the frame to the other.

In practical use and assurr ing the parts of my attachment to be in the position shown in Fig.1 it is obvious that the marker-arm will be firmly supported in the position shown, because the arm 16 will support it, and the end 17- thereof will prevent it from moving rearwardly. When the operator approaches the end of a field, he simply presses rearwardly upon the lever 23, thus moving the arched shaft 22 to throw the crank-arm 14 to a vertical position. If desired, it may be retained in this position until the machine has been reversed at the end of a field. It is then desirable to throw the marker to the complished by having the operator grasp the lever 23 and pern" it the marker to drop by ravity until the roller 15 passes out of the orwardly-inclined portion of the arched shaft. Then by pulling rearwardly upon the lever 23 with a rapid motion suflicient momentum is imparted to the crank-arm 14 and I00 other side of the frame, and this may be acthe marker ,to athrow it. to thexside 'utOWaI'd-v which it is desired .to'nrove it.-.
